RUNNING-GEAR FOR SUSPENSION-ENGINES.

SPECIFICATION forming part of Letters Patent No. 289,306, dated November 27, 1883, Application filed May 31. 1883. (No model.)

To all whom it may concerri:

Be it known that I, JAMES H. RAGE, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New 5 York, have invented new and useful Improve ments in BunningGear for Suspension-En gines, of which the following is a specification.

This invention relates to certain improvements in the running-gear of a suspension-engine, intended particularly to prevent the driving-belt from running off from its pulleys without impairing the requisite freedom of motion of the tool. r

The nature of my improvement is pointed out in the following specification, and illuslustrated in the accompanying drawings, in which I Figure 1 represents a front view. Fig. 2 is a transverse vertical section inthe plane w x, 3 20 Fig. 1. Fig. 3 is a horizontal section in the plane y Fig. 1.

Similar letters indicate corresponding parts. In these drawings, the letter A designates the framewhich forms thebeari ng forthe spindleB.

G is the tool secured in the spindle. On said spindleis mounted a pulley, a, round which ex: tends the driving-belt b. This belt moves over two movably-mounted suspension-pulleys, cc,- thence around two guidepulleys, cl (I, which are mounted in a fixed bracket, 6, and from these pulleys round the driving-pulley f. The suspension-pulleys c c are mounted on aspin- ,dle, g, which has its bearing in a box, h, and

i I in this box is firmly secured a rod, i, which is 5 suspended from one end of a cord, j. This cord extends over a pulley, k, and on its other end is secured a weight, Z. The pulley I0 is mounted in a yoke, m, from the upper end of which extends a rod, a, which is suspended from a staple, 0, secured in the ceiling or in a suitable bracket firmly secured overhead. The rod a swivels in the yoke m, and it is provided with a stop, 1), which, when the yoke is turned around, strikes either of two pins, g, which are firmly secured in the top of the yoke, Fig. 3, so as to limit the turning movement of said yoke. From the suspension-rod 7 extends a whichis secured in a staple, s,

I fixed overhead, and another safety-chain, t, g 1 extends from the weight Z to a staple, a, fixed overhead. By these safety-chains, therefore, the vertical movement of the tool is confined within certain limits, which is desirable, in order to prevent the cord j from being thrown off of its pulley k. In Fig. 1 the tool is shown in its highest position, the safety-chain 25 being stretched to its full extent, and it will be seen thatif the tool would be permitted to rise up higher, the suspension-rod i would strike the pulley 7c, and the cord j would be liable to be thrown off from its pulley. The same effect would be produced if the tool should be allowed to be drawn downward until the weight Zwould strike the pulley k, which, however, is prevented by the safety-chain r.

Heretofore the box h, which forms the bearings for the spindle of the suspension-pulleys c c, has been suspended directly from the end of the cord j, and in moving the tool in a lateral direction these pulleys are liable to be thrown into an oblique position to such an extent that the driving-belt runs off from the same. By interposing' the suspension-rod z this danger is obviated.

Ihave also found that if'the turning motion of the yoke m is not limited, the person using the tool is liable to bring the suspension-pulleys c 0 into such a position that the drivingbelt runs off from the same. This danger is avoided by the stop 10 and the pins q g, which limit the turning movement of the yoke m, as above described.

If the person operating the tool depresses the same from the position shown in the drawings, the weight Z serves to strain the drivingbelt so as to impart to the same the required grip on the pulley a, mounted on the spindle O, which carries the tool. By increasing the weight Z the grip of the driving-belt may be increased to any desired extent.

What I claim as new, and desire to secure by Letters Patent, is l 1. The combination, substantially as here- 'inbefore described, of the frame A, spindle B, tool 0, driving-belt b, suspension-pulleys 0, box 71, cord 9', and suspension-rod a, which betweeen the said cord forms the connection and the box.

2. The combination, substantially as hereinbefore described, of the frame A, spindle B,
